'-di' option not present in gcc-3.0?

NOTE: Sibiling call optimization. This pass performs tail recursion elimination, and tail and
      sibling call optimizations. The purpose of these optimizations is to reduce the
      overhead of function calls, whenever possible. 

      The source file of this pass is `sibcall.c' 

      The option `-di' causes a debugging dump of the RTL code after this pass is run.
      This dump file's name is made by appending `.sibling' to the input file name.
